SPECIFICATION forming part of Letters Patent No.. 604,849, dated May 31, 1898.

Application filed April 7, 1897. Serial No. 631,15. (No model.) Patented in Switzerland September 17, 1896, No. 13,131, and in Austria November l0, 1896, No. iti/11,529.

To a/ZZ whom t may conoermf I Be it known that I, EUGEN STEIGER, a citiz en of the Republic of Switzerland, residing at Zurich, canton of Zurich, Republic of Swit- 5 zerland, have invented new and useful lmprovements in Machines for the Multiplication of Copies of Manuscript, (for which Ihave obtained patents in Switzerland, No. 13,131, bearing date September 17, 1896, and in Ausro tria, Notti/1,529, datedNovember lO, 1896,)

of which the following is a specification.

. This invention relates to a machine for the multiplication of copies of manuscript and the like, and distinguishes itself from the hectox graphs and similar apparatuses hitherto in use in that with it no solid plastic material for the reception of the negative impression is made use of. Consequently the drawbacks inseparable from the application of a fixed zo negative surface-such as the rolling up of the printed leaves, unequal clearness and intensity of the prints, twisting of the lines, irregularity of registering, washing o of the writing from the mass, dac-are entirely done away with.

From this machine can be obtained not only hectographic prints in number to about two hundred impressions, but the apparatus also will supply black print with ordinary printers 3o inl: and in practically unlimited number Without any important alteration of the arrangement and manipulation of the machine. This kind of print is distinguished fromthat produced by means of the mimeograph and other 3 5 systems acting upon the stencil principle for the reproduction of their prints by the sharpness and accuracy of its prints, similar to lithographie reproductions, and these prints are obtainable from easily-prepared written 4o (not perforated) originals without the use of a stone or a metal plate, and possesses, moreover, the advantages hereinbefore set forth.

The machine possesses as an essential part an endless band coated with a gelatinous substance. rllhis endless band passes over rollers and is capable of taking up the writing and of imprinting it upon the copying-sheets, which band is brought into'connection with suitable devices in order to return the part 5o which has been rolled over back to the rolls and in order to returnl the pressing-roller to the initial point of its course.

Such being the nature and object of myinvention, the following is a complete description of same, reference being had to the accompanying drawings, in which- Figures 1 and 2 are elevations of the machine in different positions of the sliding plane. Fig. 3 is a plan of the machine. Fig.

4 is a longitudinal section taken on the line 6o fr, Fig. 3, and seen in the direction of the arrow Fig. 5 is a crosssection of the pressing-roller. Fig. 6 is an elevation of the support for the linking-roller. Figs. 7 and S are detailed views of the hook-levers supporting the pressing-roller, and Fig. 9 shows the movable connection of the handle-bar to the frame of the machine.

All numbers of reference denote. the same parts. 7o

The bed-plate 1 of the machine bears a softrubber plate 2, upon which the original sheet of writing or an imprinted sheet 3 is placed,

as shown bydotted lines in Fig. 3. In order to brin g the said sheet 3 exactly into register, 7 5 the machine is provided with an adjustable gage-bar 1. By means of the clamp l2,.pro vided with a soft-rubber cover G and connected by means of the shaft 7 and levers 8,

9, and 10 with the drawing-spring 11, the sheet 8o 3 is pressed firmly upon its support 2.

Four corner-pillars 18 are secured to the i bed-plate 1, of which the two 'which are placed upon the same side are respectively connected together by means of a bar 1i. Along 85 the bar 11 sleeves 1G, connected together by means of thev piece 15, are mounted to slide. The rubber rings 17 form elastic buffers limiting the course of the sleeves 1G. Upon the thickened ends of the cross-piece 15' 9o there is revolubly mounted the frame 21, formed of the two side shields 18 and reinforced by the removable handle-bar 19, as well as by the cross-piece 20. By releasing the conical screw-nuts 19:", Figs. l, 3, and 9, the handle-bar 19 may be removed from the frame 21, whereby an easy access to the parts of the machine is obtained. The springs 23, fastened on the one side to the arms 22, secured upon piece l5, and on the other side to roo the frame-piece 20, are devised to hold the frame uniformly high-that is, away from the plate 2.

In the lower part of the frame 21 is placed a pressing-roller 24, Figs. 1, 7,; and 8, the pivots of which are held in position by means of the hook-levers 25. In order to remove the roller 24, the hook-levers 25 are turned up,(see Fig. 7,) so that the pivots ofthe roller are free. On the draw-levers 26, Figs. 1, 3, and 4, revolubly adjusted in the upper part of the frame, there is supported a second roller 27 Around the two rollers 24 and 27 there is placed an endless band 2S, capable of receiving the writing, in connection with which the springs 29, supported on the one hand by means of regulating-screws on the frame 21 and on the other hand by means of the drawlever 26, produce the tension of the band 28. The `-band 28 consists of paper parchment coated with a gelatinous substance.

The machine operates as follows: Let it be assumed that the machine is'in the position shown in Fig. 1 and that the original document written with hectographic ink has been placed in the machine and held down by means of the clamp 12. Now the right hand of the operator seizes the handle bar 19, presses the fame 21 down upon the original sheet, and, maintaining the pressure, pulls the frame in the direction of the arrow, Fig. 1. In consequence of this the band 28 rolls .over the original inscription and takes the writing in a similar manner to that in which the hectographic mass takes up the inscription upon itself. Arrived at the opposite end of the machine (see Fig. 3) the handle-bar 19 is released, upon which the springs 23 lift the frame 214 from the plate 2 until the piece 2O strikes against the arms 30, fixed to the piece 15. On the advance of the frame 21 in the direction of the arrow in Fig. 1 the spiral spring 34, one end of which is attached to the pivot 33 of the toothed wheel 32 and the other end of which is attached to the wheel 32, (see Fig. 4,) is wound by means of the toothed pinion 3l, fixed upon the shaft of the pressing-roller 24, and of the gear-wheel 32, revolubly fixed on the frame 21. When the frame 21 is pulled under pressure in the direction of the arrow, Fig. 1, the roller 24 revolves and the pinion 31 is turned by the shaft of the roller 24. `As soon as upon the completed course of the frame 21 and raising the same the roller 24 has been lifted up from the plate 2- the spring 34 is released and causes the roller 24 to revolve back by means of the toothed wheels 32 and 31, so that the band 28, with the writing, returns again into the position which it had at the beginning of the operation. Shortly before the completion of the movement of the frame 21 the right-hand reinforcement 35 of the piece 15 comes into connection with the bent arm 36 of the angle- Iever 10, Figs.1 and 2, and pushes down this arm. IIereby the clamp 12, connected with c very long time.

the lever 10 through the parts 7, 8, and 9, is raised, so that the original writing can be removed and a fresh sheet 3 can be placed upon the plate 2. The frame 2O is then pushed back to the left without pressing upon the handle-bar 19, on which the spring 11 immediately presses the clamp 12 down again as soon as the reinforcement 35 releases the arm 36. The frame 2l is then pressed down and again lpulled forward, whereupon the band, with the writing 28, prints itself off upon the sheet of paper, and thus is produced the first impression. At the conclusion of the move- Ament of the frame 21 the clamp 12 is again take place. Inthis'manner the operation is repeated until the required number of impressions have been taken.

In order to 'prevent on the release of the spring 34 a turning b ack of the rollers 24 and 27 beyond the required point, there is placed upon the wheel 32 a pinV 37, and upon the frame 21 an angular brake-lever 39. The upper end of the draw-bar 40 is connected to the brake-lever, whose lower end is in the form of a hook. The spring 11 draws the bar 40 backward, whereby the brake-lever 39 is lightly pressed on the side brake-disk 42 of the roller 27. When the wheel 32 springs back, the pin 37 engages in the hook end of the bar 40, turns the same, and thereby also 8o raised, so that the exchange of the sheets can the brake-lever 39, so that the roller 27 is" braked. In order that the spring 34 should never entirely release itself, the wheel 32 has a pin 38, which limits the revolution of the wheel 32 by striking on the plate 43. When the roll 27 is taken out, the pin 44 of the arm 40 prevents too great a dropping of the bar 40, because it engages on the frame 21.

In order to be able to produce autographic copies in black upon the aforesaid machine, the same is provided with an inking-roller 45, Figs.1 and 6. On the piece 15' are secured two bearing-supports 47, each provided with an open inserting-slot 46, in which the pivots of the inking-roller 45 is placed. The levers 48, pivoted to the supports 47, bear IOO IIO

springs 49, which engage over the pivots ofv does not act in conjunction with a hard surface. In order to maintainthe parchmentband 28 moist and iexible, the soft cover 50, which preferably consists of felt,is to be moistened from time to time; but it remains moist a Besides the addition ofy the inking-roller 45 and cover 50 the machine is the same as above described.

After the gelatinousparchment band 28 has taken up the inscription upon itself by being rolled over the original Writing prepared with suitable ink the inking-roller45 is placed in the supports 47. At the moment when the band 28 begins to travel by pulling the frame 21 the inking-roller 45 transmits the ink to the -Writing on the face of the band 28, receiving thereby impressions in black.

Asamatterof course to obtain heetographie copies hectographic ink and to obtain black copies autographic ink have to be used to prepare the original Writing. The inking-roller is` only necessary in the latter case and has to be blackened with ordinary printers ink.

" Having now particularly described and ascertained the nature of my said invention and in what manner the same is to be performed, I declare that what I claim is- 1. In combination, the table, the guideframe, the carrier moving thereon comprising a pivoted portion, the traveling band, therollers therefor on the carrier, the driving-disk having connections tothe band for driving the same through contact with the sheet, the spring for returning the band to normal position and means for lifting the pivoted carrierframe when it reaches the end of its course 3.
